The strength of the 2.3 µ CO band in weak-G-band stars.
Abstract
Broad-hand infrared magnitudes and intermediate-band CO indices for 29 weak-C-band stars in the field are presented. The (J- K) color indices of the stars correspond to those of early K giants, in agreement with descriptions of their spectra. All the stars display very weak CO absorption relative to field giants. This confirms a previous conclusion that the weak-C-band stars are deficient in carbon by large factors. Key words: infrared photometry-CO band-weak-C-band stars
